DVD problem during installation of 12.1 on laptop

Installing OpenSUSE 12.1 64-bit from ‘Gnome Live CD’. HW is a new HP Pavilion g6 laptop; installing onto an external USB HDD; the DVD drive is described as HP DVD-RAM UJ8B1.
All seemed fine until it got to the partitioning stage. While I was considering what I wanted, the DVD slows down and stops; then starts up again when I use the mouse to select the partitioning I want. After two or three cycles the DVD goes into an odd state where it is making a noise but isn’t up to speed. I had to abandon the installation process at that point. When I tried again, exactly the same thing happened at the same point. It could be a faulty DVD drive, but I actually think the installer may be at fault. The DVD drive seems fine the rest of the time (but I admit it hasn’t had a lot of use yet).
Is this a problem that anyone else has seen ?
BTW, I successfully installed 12.1 by transferring the DVD to a USB Stick…

did you check, before the install, the absolute correctness of the
install image on the drive this way: http://tinyurl.com/455hbml

if you did not, then that could be the problem: you were trying to
install from a faulty install disk image…

otherwise, it is (unfortunately) not unusual for CD/DVD writers to burn
an image they later read incorrectly…it seem that manufacturers of
disk burners buy the absolutely cheapest hardware possible…yours may
be new but need replacing…

if there was CD write problem at some point in the disk there (or just
a big fat fingerprint or scratch, or manufacturing defect in the disk
itself) it might go into searching around on the disk trying to read it…

one thing is that not all disks are created equally…some of those you
buy in bulk (say 25 or more on the same spindle) with either no-name or
a brand you have never heard of, at discount houses…well, some of
those you might have to throw away a third of them as bad burns…

good on you for figuring out an alternative, and getting done what you
want to do…

WAIT! you wrote “Gnome Live CD” and also “transferring the DVD to a USB
Stick” did you have both a CD and a DVD? did you check both?

No, mea culpa. But I tried to just now, and it didn’t work; the screen blanked (I set ‘nomodeset’ as an option); then displayed some text (Loading KIWI…],
so I don’t really know; maybe the CD is faulty. I received it from a local (UK) supplier.
The USB image which worked OK was from this CD, though…

No, I just have the one disk. It’s labelled “LIVE CD”, but with ~8GB on it, I call it a DVD !

Thanks for the response. I’ll leave it for now, as it’s installed and working. If I find a better way to
verify the CD, I’d try it.

no. you boot from the CD and when the first green screen comes up you
use the arrow keys to move the highlight down to “Check Installation
Media” and then press enter…

if you are seeing a blank screen at that point i think you may have a
hardware…well, wait…i have no idea what might be going on…and,
if you are seeing loading kiwi i think maybe you are trying to boot from
the USB key…remove it, and in the bios select to boot from the CD
drive…THEN at the first green screen . . .

You are using some strange thing that is not what we use. Our DVD is about
4 GB, single layer.
